Form, in the preparation method of base 51, can not be gold-plated to the implementation of its surface etc., there is higher resistance.Also, environment temperature is got over
It is low, then bigger electric current (such as being up to 200mA or so) is flowed through in heating circuit 31.Therefore, according to due to interior
Voltage caused by the dead resistance of portion's wiring 64 reduces, (stream in the case of being low temperature in the environment temperature of quartz oscillation element 2
In the case of crossing larger current) and high temperature in the case of (in the case of flowing only through smaller current), the ground of heater element 3
Change.Specifically, for example, the electric current flowed through in heating circuit 31 be 200mA, the dead resistance of internal wiring 64 be 0.5
In the case of Ω, the ground of heater element 3 changes 100mV.On the other hand, without flow through heater element 3 in circuit element 4

621 are exposed to receiving space S respectively with wiring 651,652, so, in the manufacture of base 51, its surface can be implemented to plate
Gold, actually its surface is implemented gold-plated.Therefore, ground wire internal terminal 621 and wiring 651,652 fully inhibit electricity respectively
Resistance.Thus, by the resistance in the path that ground wire terminal 331 and ground wire terminal 431 are connected via connecting wiring 7 suppress well below
The resistance in the path of ground wire terminal 331 and ground wire terminal 431 is connected via internal wiring 64.Thus, shaking according to this structure
